The inclinationof' the axis is the driving shaft about the middle -of the sion housing.In'the case of a four point suspension of the engine the mounting itselfisgeneraily executed in such a way that the engineismoimtcdelasticallyatallpointson simportingsurfaces r*arrangedonbothsidesofthecenterlineofthe,

without', on the other hand, preventing the ostili--Y lations of theengine around the longitudinal axis. According to the invention 'this isobtained. by

the fact that the engine is connected with time frame of the car bymeans 'of links, that is, rods, which are placed on'both sides of theengine housing and mounted rotatably to the housing' Y as well as'tg theframe of the car. Thedrawing 'shows,'asa example, one form ofconstructions!! the inven on, in which'Fig-ure 1 is the engineY housingvand the arrangement of the links in a side view; Figure 2 is thearrangement of the linksinaplanviemFigureMstherearviewofx the enginemounting,y and Figure 4 is the front `view of the mounting of theengine.

Theframe ,of the car consists of the' side members i and 2, which areconnected together in vfront by across member 3 and at the locationoftheonhousingl oftheengine iby a cross member 6. As a result of theform which has been given to it the cross member 8 forms two inclinedsurfaces 6a and 8b, which serve for the mounting of the e'ngine.l Forthis purpose a cross member 1 with' surfaces 'iaand'lb bent upward isfastened below the transmission housing, these bent up surfaces runningparallel with the inclined surfaces ya and 6b. By means o f thesesurfaces the engine housing is fastened by means of=the screws i0 and Iltothe surfaces'la and 6b, with the interposition of the rubber bui'-fers l and 9.

For the mounting at the front ;end, supporting isllbiected due to theunev 'bymeansoftheboltsilaandilhThefasteningatboththefrontandreargendsiseifectedin, sucha way that theengine housing-mmounted on all s idesg- Also the inclinations of therear ysupporting surfaces Scand lb and of thefront ones iland Il areselected in such a waythat the engine can osciliate aroundthelongitudinalaxis ishowinFig. l. Inthepresent case this axis, startingfrom the upper front endo! the engine, runs inclined backward and.inrsects theon housing -approximatell lyintheaxisofthesame. y

l ds a result of the all aroimd elastic support, in the acceleration'andbraking of the car there occursa movement of the engine housing withArelation to the.i'rame of the car. In order to20 prevent this, on theright and left sides of the part 2l of the engine housing are mountedlinks Il and 22-,which are articulated to'the engine housing itself andto the projections 23 and 2l.

-whicharefastened tothe cross member lin any 25 A ,suitablemanner."'1'hese links extend substan-| tially parallel to the axis iland prevent movements of'the engine housing in the direction of thelongitudinal axis without, on the other hand, interfering with theoscillations or the housing 3 which take place around the axis I9.

It is known to make the fender support in the form of a throughsupporting beam and to' moimt it elastically on the front cross memberof the car. In that way the torsions to/which lthe frame 35 of thehigh-s, way, are prevented from being transmitted to the fenders. Onaccount of the elasticmountins of this support it is necessary moreoverto connect itwith e, point wiiiciiisnot innueneed by the 0 torsions ofthe frame and as far as possible also does not have any longitudinalmovement with relation to the frame.- In the four point suspensionshown, in which, by the use of the links 2| and 22 all longitudinalmovement oftheengine 5 i housing is prevented, Athe above requirementsare fulililed by the intersection of the axis of oscillation is with thefront wall. The point thus designated does not, in fact, undergo anyoscil- 'lationa It can'therefore be used for the fasten- 5 ing of thefender support.

vIn the drawing the fender support is desig hated by 25. It is Imountedelastically on the ross member. 3 in a'. known nanner-with theinterpontion of a rubberbuer 28. Also it is 55 connected to the-irontend ot the engine housing ent that oscillations oi. the engine,accommo-l dated at the points of resilient support, are not imparted tothe fender support and frame, and that in the same manner weaving of the`side frame members due to road action, occurs without affecting theposition of the fender and engine. i

I claim: v 1. In combination a supporting'structure. an
